Abstract: Novel oxime ethers of formula (I) are claimed as are also (i) prepn. of (I) by reaction of an oxime ether alcohol of formula (II) with an alkyne of formula (III) in presence of a base; and (ii) use of (i) as a comonomer in the prodn. of polymeric coatings or adhesives. R and R = H, 1-20C alkyl, 4-10C cycloalkyl, or 6-10C aryl or together form a 3-14C bridge; R = H, 1-4C alkyl or phenyl opt. with an inert substit.; n = 1-100; and A = 2-10C alkylene opt. with an inert substit.

Abstract: Pyrocatechol monoethers or pyrocatechols of the general formula Ia and Ib, respectively, (R and R = H or C1-C8-hydrocarbon radicals; R = C1-C8-hydrocarbon radical) are prepared by a) reacting a 2-hydroxycyclohexanone dialkyl ketal II in the gas phase in the presence of a platinum metal or of a compound of one of these metals as catalyst, so as to obtain the compounds Ia, and b) carrying out step a) in the presence of water so as to obtain the compounds Ib. The products can be used as intermediates for the synthesis of pharmaceutical products, odoriferous substances and flavourings.

Abstract: Polyurethane vinyl ethers are obtainable by reacting A) 1 NCO equivalent of one or more isocyanurate-containing polyisocyanates with B) 0.01-1.0 OH equivalent of one or more monohydroxyvinyl ethers and C) 0-0.99 equivalent of functional groups of further compounds, which groups are reactive with OCN.
